Obviously I'm real late to the party here, but I do remember seeing this ride at the Los Angeles county fair when I was a young child, but it was called Calypso for some reason. That same fair also had a Chance Turbo.
I seem to even remember riding the Calypso/Meter... I have a memory of it generally being very, very mild, but if you were in the wrong place at the wrong time, you'd really get slammed to the side quite hard.
Sadly, I was too young to ride the Turbo... one of my biggest regrets now. There's reportedly a company in California restoring a Turbo, but I don't think it's yet been taken on the road.
